  1. We all get terrible response times waiting for "ajax.googleapis.com" to timeout today 2015-06-25.

    C:\Users\Jeff>ping ajax.googleapis.com

    Pinging googleapis.l.google.com [216.58.216.170] with 32 bytes of data:
    Request timed out.
    Request timed out.
    Request timed out

    This is a google issue, not Techspot.com

    Still going on? Didn't have the problem here but we use Google's CDN for those files assuming they won't ever have an issue, among other reasons.

    Btw: translate.googleapis.com fails also as that's a subdomain of googleapis.com

    hmm; perhaps but not exclusively else we would not be stalling on the ajax.googleapis.com

    @Julio Franco
    Just been reading an article re CDNs http://weblogs.asp.net/jongalloway/using-cdn-hosted-jquery-with-a-local-fall-back-copy
    which notes
    Code:
    <script type="text/javascript" src="http://ajax.microsoft.com/ajax/jquery/jquery-1.3.2.min.js"></script>
    <script type="text/javascript">
    if (typeof jQuery == 'undefined')
    {
      document.write(unescape("%3Cscript src='/Scripts/jquery-1.3.2.min.js' type='text/javascript'%3E%3C/script%3E"));
    }
    </script>
    
    Of course, the privately hosted copy invocation is very specific to the api being invoked, but you get the idea.

    I've switched to a different CDN on the forums until Google resolves the problem. Quick question, was the slowdown problem (due to ajax.googleapis.com not resolving) only noticeable on the main site, the forum, or both?

    Thanks!

    forum->Most Recent Topics.

    the DNS resolves correctly, but the access timesout, hence the stall.

    Should be solved now because we switched over to a combination of our own CDN and Microsoft's.

    My question was because the CDN fallback (as suggested above) was already part of the forum configuration but it's not working as intended, which is also mentioned in some dev discussion boards like stackoverflow.

    A little history on this issue.

    when this all started ajax.googleapis.com was located at 216.58.216.138

    Today it's at
    nslookup ajax.googleapis.com
    Non-authoritative answer:
    Server: dns-cac-lb-01.rr.com
    Address: 209.18.47.61
    Name: googleapis.l.google.com
    Addresses: 2607:f8b0:400e:c04::5f
    74.125.25.95 <<<
    Aliases: ajax.googleapis.com​

    Tracert ajax.googleapis.com now shows

    over a maximum of 30 hops:

    now NODE#9 is ~ the last node seen yesterday during the failure.

    So who is 64.233.174.238
    NetRange: 64.233.160.0 - 64.233.191.255
    CIDR: 64.233.160.0/19
    NetName: GOOGLE
    NetHandle: NET-64-233-160-0-1
    Parent: NET64 (NET-64-0-0-0-0)
    NetType: Direct Allocation
    OriginAS:
    Organization: Google Inc. (GOGL)
    RegDate: 2003-08-18
    Updated: 2012-02-24
    Ref: http://whois.arin.net/rest/net/NET-64-233-160-0-1
    OrgName: Google Inc.
    OrgId: GOGL
    Address: 1600 Amphitheatre Parkway
    City: Mountain View
    StateProv: CA
    PostalCode: 94043
    Country: US​

    So the failure was entirely within GOOGLE - - the guys who are suppose to know how. It's interesting to see that these addresses
    64.233.174.238, 64.233.175.150, 209.85.143.150, 209.85.143.127​
    do not have corresponding DNS names - - it's legit (as it's internal to google) but kind of sad too.
